Draba (Brassicaceae). Most Draba are D-70 germinators. A comparison of the high germination of DS to low germination of fresh seed was given in Table 5-1. Sowing of fresh seed at 70 not only gives low germination, but is often fatal. D. brunifolia germ. 70(2/3 on 8th d) and 40-70(2/3 in 2-14 d).
Seed Germination Theory and Practice, 2nd ed., Ch. 20, Draba p. 135. Quoted exactly. Every value on this card comes from this record, except the difficulty rating, which is ours; the step names come from a fixed list.

Protocol 2

DerivedN. C. Deno, 1993

Difficulty Moderate Rated by us, not by the source.

Start around December 22, 2026 for a May 3 last frost.

  1. Cold moist stratification

    Duration: 90 daysTemperature: 40°F 4°C

  2. Warm moist stratification

    Duration: 90 daysTemperature: 70°F 21°C

about 3 months from start to step 2. Germination happens during step 2, in 14 days.

67% germination in 2–14 days.
